*** Depending on actual local conditions, extended maximum recoating intervals may apply.
Please contact HEMPEL for further advice.
Maximum recoating intervals:
If the maximum recoating interval is exceeded, whatever the subsequent coat,
roughening of the surface is necessary to ensure optimum intercoat adhesion or in the
case of recoating with coatings other than HEMPADUR, apply a (thin) additional coat of
HEMPADUR 45150 within the above directions for recoating.
Long recoating intervals:
A completely clean surface is mandatory to ensure intercoat adhesion, especially in the
case of long recoating intervals. Any dirt, oil and grease have to be removed with eg
suitable detergent followed by high pressure fresh water cleaning. Salts to be removed by
fresh water hosing.
Any degraded surface layer, as a result of a long exposure period, must be removed as
well. Water jetting may be relevant to remove any degraded surface layer and may also
replace the above-mentioned cleaning methods when properly executed. Consult HEMPEL
for specific advice if in doubt.
To check whether the quality of the surface cleaning is adequate, a test patch may be
relevant.
